The on-site compressors use dry gas seals; there are issues regarding the source of the dry gas used
Thread Content
Currently, the air compressor on the unit is equipped with a dry gas seal; the primary sealing gas (nitrogen) comes from the low-pressure nitrogen pipeline network, at around 0.5–0.6 bar (G)； There is interest in using medium-pressure nitrogen at around 35 bar, which would be used as the primary sealing gas after passing through a pressure regulator; however, there is concern that a failure of the pressure regulator could result in too high gas pressure, thereby affecting the sealing performance. I wonder if anyone has used this in practical applications on site?

Isn’t the main sealing gas supposed to be a medium gas?
Rich gas compressor? Is there a lot of liquid involved?
